PATENT OFFICE.

MORRIS G. ROSENTHAL, or CINCINNATI, oHIo.

Be it known that I, MORRIS G. RosENTHAL, a citizen of the United States, residing at Cincinnati, county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Label-Feeding Means for Automatic Label and Patch Stitching Machines, of whichrthe following is a specification.

T1118 invention relates to improvements in label feeding means for automatic label and patch stitching machines. The inven-' tion relates particularly to label feeding means adapted to deliver labels under the label presser foot of a machine like thatap- 1 pearing Rosenthal at al. Patent No.

1,293,554 of February 4, 1919.

The objects of the invention are to simplify the delivery or feed mechanism of the labels to such a machine. A further object is to provide a semi-automatic means for thus placing the labels in position, the same being manually controlled except for release devices, 'thereby eliminating much of the mechanism and eliminating obstructions to p Y the operator without materially lessening the speed of the operations. 7 I

I accomplish the objects of my invention by the devices and means described in the following specification.

A structure whichis a preferred embodimentof my invention is clearly illustrated in the accompanying drawing, adapted especially to the machine of the patent above referred to, in which:

Figure I is a perspective view of the feed means as applied to asewing machine of the class indicated, the parts of the sewing ma chine being shown in fragment. 7

Fig. II is a side elevation from the left of the view of Fig. I.

Fig. III is a detail transverse sectional view taken on line 33 of Figs. I, II and IV,

showing details of the fingers of the label follower.

Fig; IV is an enlarged detail longitudinal sectional view through the feed mechanism taken on line l -l ofFigs. I and III, showing the feed means in the position which it I assumes after a label has been stitched and withdrawn, .or atthe beginning of operations.

-Fig. V is a longitudinal sectional view similar to Fig. IV showing the label follower The invention is clearly defined and pointed out in the claims.

withdrawn to receive a label, the label being.

In the drawing the sectional views are taken looking in the direction of the little arrows at the ends of the section lines and slmilar numerals of reference refer to similar parts throughout the several views.

Considering the numbered parts of the draw1ng,1 is the bed of the machine, 2 the work holder plate, 3, the lower part of the sewing machine head, 4 the label carrier, 5 the label retaining shoe or guide foot, and 6 the label slide orchute through which the label is delivered, all ofwhich are substantially the same as the parts appearing in the 'Rosenthal' patent above referred to and which it will not be necessary to here detail.

Because my invention does not pertain to such details, Irefer to the said patent for a full 1 understanding of the mechanism for stitching and aiiixing the label.

7 isthe label followerdisposed in the label chute 6 and has downwardly projecting fingers'8 which engage the rear edge of the label and carrythe same'forward. A post 9 is secured to this slide extending, upwardly therefrom.

On the post 9 is pivoted the latch lever 10 is provided with a latch catch 15 on its under 7 side that engages over the front end of the label chute'to hold the label follower in re tracted position. V I

' On the side of the sewing machine head 3 is secured a stop arm 17 having a downwar'dly'projecting portion '18 to engage the forward end 16 of thelatch lever 10. The relation of these parts clearly appears in Figs IV,V and VI in the different steps of their operation.

An adjustable stop 19 is secured in place by the set screw 20 to limit the forward advance of the label follower.

From this description it is believed that the functions of the various parts will be understood when the operation is definitely pointed out. The sectional view of Fig. IV shows the machine after the stitching oper ation and after the l: bel is removed ready to begin operations for the next label. The operator by the hook 14 withdraws the latch lever 10 into engagement by catch 15 with the front end of the label chute 6, thereby withdrawing the label follower 7 into label receiving position. The label 21 is then placed in the position seen in side View in V, and is ready to be fedunder the label retaining shoe when the machine is manipulated.

The work holder plate and label shoe are then elevated by means described and referred to in the said patent above referred to, and as the work holder plate rises. the end 16 of the lever 10 contacts with the stop 17 in the position indicated by dotted lines in Fig. VI. The end of the lever 16 then engages the downwardly projecting portion 18 of the stop 17 afterthe catch 15is released from the front end of the label feeding chute, and a small advance motion is permitted until the end 16 of the lever engages the downwardly projecting catch portion 18 and the preliminary label feed is stopped at that point. The catch 15 is then on top of the chute in a disengaged posi tion. hen the machine has already been operated, the finished work with the label stitched thereon is withdrawn. A piece of work, as a garmentto be labeled, is moved into place to receive the label.

At this juncture the foot of the machine is dropped down and, owing to the slight engagement of the end 16 of the lever by the catch 18,- said end is immediately released and the label is shot under the label retaining shoe while it is descending and is caught and held fort he next stitching operation.

From this description it will be seen'that the machine is automatic to the extent of releasing the manually-operated devices so that the spring 12 performs its function of feeding the label at the proper time. As my invention does not relate to the parts which hold and stitch the label, I have not de-' scribed the same in detail. My invention might be used with various kinds of stitching devices, I having shown the same merely sulliciently in this connection for the purpose of explaining my invention, which is an improvementmerely in the step of feeding the label.

It will be observed that the spring12 performs many functions in this behalf. It feeds the label follower; it actuates the lever so that it islatched in the withdrawn position; it also acts to actuate the lever so that it serves to move the label into its preliminary fed position. .VVhen the shoe is dropped down it instantly shoots a label into place by actuating the label follower, as
